When the trap of addiction snaps shut, does it ever release you? Can you ever pry yourself loose? Scott Steffensen (BYU Dept. of Psychology) and Mark Butler (BYU Dept. of Marriage and Family Therapy) study the scientific and therapeutic aspects of addiction-chemical or otherwise. What they have to say may offer hope in the face of hopelessness. Also joining us for this interview is a recovering addict we'll call David whose family life collapsed because of his addiction to pornography. He'll tell us about turning the corner and seeking permanent change.—Original airdate: 8/2/2006
